Alkyd paint is the life of corrosion common atmospheric corrosion environment because of paint, used more often, users encounter a variety of problems. The film is normal alkyd paint smooth, but some people have met the film powder phenomenon, today we have to understand the reason of alkyd paint film powder the reasons and solutions. A thinner, improper paint durability should be lost, thus lead to the occurrence of powder. Methods: suitable diluent selection before construction, if not sure, ask what kind of diluent can consult the manufacturer and usage.
There may be two reasons: alkyd paint product is well mixed before, did not achieve the full integration of the state, the film for a long time under the sunlight, the individual is not well mixed pigment particles area, gradually loosening or aging, the area gradually increased, the late film surface will appear, powdered natural exfoliation state. Processing method: construction paint mixing is generally needed for curing. If the construction procedure is not clear, consulting and technical personnel.
How to deal with the film has powder: 1, an important construction environment right, especially after coating for a period of time, we must resolutely avoid exposure in too high temperature, sunlight environment. 2, mild powder can take fast polishing method to remove powder region; serious powder can be used the crude wax polish, remove the powder layer; if it is severe powder, you must choose to repair the way of spraying.
Alkyd paint itself smooth, decorative effect is good, once the construction of problems, light affect the appearance effect, heavy corrosion resistance performance, redo paint, so before construction must pay attention to these possible causes
